Well, if you were a Unix guy, then you would recognize Motif Widgets. It looks like you are missing a package called libmotif3.
tgalati4@Dell600m-mint14 ~ $ apt-cache search libmotif
libmotif-dev - Open Motif - development files
libmotif4 - Open Motif - shared libraries
libmotif4-dbg - Open Motif - shared libraries
It looks like the default Ubuntu distribution only has libmotif4.
So, adding another log to the fire:
1. Modify build scripts to point to libmotif4 and hope it works. ln -s libmotif3 libmotif4
2. Compile libmotif3 in a current Ubuntu build environment. "Open Motif" should have source code available somewhere.
3. Find precompiled binaries (*.deb) of libmotif3 from someone else who faced a similar problem.
4. Find libmotif3 on an older version of Ubuntu and build that workstation to use for development. I know Jaunty has it.
I love sitting by the fireplace.
